A 25 kg child bounces on a pogo stick. The pogo stick has a spring with spring constant 2.0x10^4 N/m. When the child makes a nice big bounce, he finds that at the bottom of the bounce he is accelerating upwards at 9.8 m/s^2. How much is the spring compressed?
A pogo stick has a spring with a force constant of 2.50 × 104 N/m , which can be compressed 12 cm. To what maximum height, in meters above the compressed position of the spring, can a child jump with the stick using only the maximum elastic potential energy in the spring, if the child and stick have a combined mass of 35 kg?
A 40.0 kg boy jumps on a 4.75 kg pogo stick with spring constant 3650 N/m. (a) Find the angular frequency. ? = rad/s (b) Find the frequency. f = Hz (c) Find the period of the boy's motion. T = s
2 pts A toy manufacturer wishes to design a pogo stick so that when a child of mass 44.0 kg compresses the spring of the stick by 13.5 cm, the maximum height reached by the child is 28.4 cm. What spring constant should the manufacturer use? (Assume that mass of the stick is small compared to the child.)
A 0.19 kg mass is held at rest against a compressed spring with a spring constant of 103 N/m. When released, the mass leaves the spring with a speed of 6.28 m/s. Assuming that the spring force if wholly responsible for changing the motion of the mass, by what distance was the spring initially compressed from its equilibrium position?
A 68-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.77 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.8 s, and then comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during the first 0.77 s of the elevator's ascent?...
3. A spring with a force constant of 7.0 N/m is hung vertically and then compressed by 0.125 m. If a 0.100 kg mass is attached to the spring while compressed by 0.125 m, what will the speed of the mass be when it is passing a point 0.175 m below the compression point (i.e. 0.050 m or 5.0 cm below the equilibrium point)?
if you stand on a pogo stick you note that its spring loaded foot is pushed in about 18cm. if you bounce gently up and down, what is your approximate oscillation frequency? The answer is 1.2 Hz but please show work
ping constant is 2000 N/m. How By Is Stored in the spring when it is compressed 6 cm as the dart is inserted into the barrel? -4. In an NCAA swim meet, Ruth Davis jumps from the 10-m diving board with an initial upward velocity of 2 m/s. What is her speed as she hits the water? 5. A cannonball that is fired upward at 45 deg is seen to rise to a maximum harti 1000 m. Assume that air...
In the figure, a 2.6 kg block is accelerated from rest by a compressed spring of spring constant 660 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction ?k = 0.272. The frictional force stops the block in distance D = 7.9 m. What are (a) the increase in the thermal energy of the block In the figure, a 2.6 kg block is accelerated from...
